Product details
Overview
ISL59830IAZ from Intersil is a triple single-supply video driver IC designed for RGB/YPbPr analog video signal amplification and DC-coupled 75Ω line driving. It operates from a single +3.3V supply, integrates an internal charge pump to generate –1.6V VEE, delivers fixed 6dB (2×) gain per channel, supports three-state outputs, and achieves 50MHz 0.1dB bandwidth - enabling NTSC/PAL and DVD player video output without external gain resistors or DC-blocking capacitors.
For engineers reviewing the ISL59830IAZ datasheet, ISL59830IAZ pinout, ISL59830IAZ application, or ISL59830IAZ equivalent, key selection criteria include its true single-supply operation with integrated negative rail generation, 0.07% differential gain / 0.06° differential phase accuracy at 150Ω load, enable/disable control with 200ns turn-on time, and QSOP-16 package compatibility with legacy video routing designs.
Technical Context
The ISL59830IAZ integrates three independent voltage-feedback amplifiers fabricated on a dielectrically isolated 5V Bi-CMOS process, each with rail-to-rail input (0.15V below VEE to 100mV below VCC) and output swing limited to ~300mV from rails into 150Ω. Its internal 168MHz charge pump generates a regulated –1.6V VEE rail referenced to half of VCC, eliminating need for external negative supplies in NTSC sync pulse handling.
Each amplifier features folded-cascode input stage to minimize Miller capacitance effects, a second differential gain stage, and a proprietary common-emitter output stage delivering <2Ω low-frequency output impedance - critical for stable 75Ω double-terminated cable driving while maintaining <5dB peaking into 10pF + 1kΩ loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | +3.0V to +3.6V single supply; enables full NTSC/PAL video signal swing including negative sync pulses without split supplies |
| Gain | Fixed 2× (6dB); eliminates external gain-setting resistors and associated layout sensitivity or mismatch |
| 0.1dB Bandwidth | 50MHz at 2VPP output; ensures minimal amplitude error across standard-definition video baseband (0–5MHz) |
| Differential Gain | 0.07% at 150Ω load; preserves color fidelity in RGB/YPbPr systems by minimizing amplitude nonlinearity vs. DC level |
| Differential Phase | 0.06° at 150Ω load; maintains chrominance timing integrity critical for broadcast-quality video reproduction |
| Output Impedance | <2Ω enabled, >10MΩ three-stated; allows direct 75Ω back-termination without series isolation resistors |
| Enable/Disable Time | 200ns turn-on, 25ns turn-off; supports fast blanking or power-gating in multi-channel video systems |
Pinout & Package
ISL59830IAZ is housed in a 16-lead QSOP (Shrink Small Outline Plastic) package per drawing M16.15A, 0.150" wide body, RoHS-compliant Pb-free plus anneal finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RIN, GIN, BIN | Analog video input (Red, Green, Blue) | High-impedance (1–15MΩ) inputs accepting ±1V swing; share common reference node at REF pin |
| REF | DC-level shift reference | Low-impedance node setting common-mode offset for all three channels; 0.6V typical shift for back-porch alignment |
| VEE | Charge pump substrate output | Provides –1.6V regulated negative rail; must be bypassed with 0.1µF ceramic capacitor to GND |
| GND / DGND | Analog / charge pump ground | Separate ground pins reduce coupling between analog signal path and switching charge pump noise |
| VEEOUT / DVCC | Charge pump output / supply | DVCC powers internal oscillator; VEEOUT connects to VEE pin - both require local 0.1µF bypassing |
| VCC (pins 11,13) | Positive supply | +3.3V main supply; dual-pin configuration reduces IR drop and improves PSRR |
| EN | Enable control | TTL/CMOS-compatible input; <0.8V = enabled, >2.0V = disabled; disables amplifiers but keeps charge pump active |
| ROUT, GOUT, BOUT | Analog video outputs | Three-state capable; high-Z state isolates outputs during blanking or system sleep modes |
| NC (pin 10) | No connect | Not internally bonded; must remain unconnected per datasheet |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple video buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL59833IAZ | PIN-compatible upgrade; improved 0.05% dG / 0.04° dP, lower 15mA quiescent current, same QSOP-16 footprint | Direct replacement for new designs requiring tighter video specs or lower power; retains identical REF/EN/VEE functionality | Select ISL59833IAZ when upgrading legacy ISL59830IAZ-based systems for enhanced color accuracy or thermal margin. |
| EL1881CSZ | Triple 6dB video buffer; requires external –5V supply, no integrated charge pump; 40MHz 0.1dB bandwidth, 0.1% dG | Suitable only where negative supply already exists; not drop-in due to different pinout and supply architecture | Choose EL1881CSZ only if existing design includes –5V rail and board layout cannot accommodate ISL59830IAZ's VEE/DVCC/VEEOUT connections. |
Compared with ISL59830IAZ, ISL59833IAZ offers measurable improvements in differential gain/phase and power efficiency while maintaining pin and function compatibility, whereas EL1881CSZ demands redesign for external negative supply and provides lower bandwidth - making ISL59830IAZ uniquely suited for compact, single-supply video systems.

FAQ
What is the primary function of the ISL59830IAZ in a video system?
The ISL59830IAZ serves as a triple-channel, single-supply video driver that amplifies and conditions RGB or YPbPr analog video signals for 75Ω transmission lines. It integrates a charge pump to generate a –1.6V negative rail, enabling true DC-coupled operation without external negative supplies - essential for preserving NTSC sync pulses and back-porch levels. Each channel delivers fixed 2× gain with exceptional differential gain (0.07%) and phase (0.06°) accuracy at 150Ω load, making ISL59830IAZ ideal for broadcast-quality video routing.
Can the ISL59830IAZ operate without an external negative power supply?
Yes, the ISL59830IAZ can operate without an external negative power supply. It incorporates an internal 168MHz charge pump that generates a regulated –1.6V VEE rail from a single +3.3V supply. This internal negative rail allows full-swing video signal handling - including negative-going sync pulses in NTSC - while eliminating the need for discrete negative regulators or additional power planes. The VEE pin must be bypassed with a 0.1µF ceramic capacitor to GND, and the DVCC/VEEOUT pins require proper decoupling per the datasheet layout guidelines.
How does the REF pin affect video signal level in the ISL59830IAZ?
The REF pin in the ISL59830IAZ sets the DC reference point for all three amplifier channels, enabling precise vertical blanking interval (VBI) or back-porch alignment. Applying a voltage (e.g., 0.6V) to REF shifts the output signal down by that amount relative to the input - so a 0.6V REF produces a –0.6V DC offset on the output. This is critical for matching CRT or LCD display timing requirements. The REF node has low impedance tolerance: any series resistance introduces cross-talk and gain error, so it must be driven by a low-impedance source such as an emitter follower (e.g., MMBT3904) or buffered DAC output.
What is the significance of the three-state output feature in the ISL59830IAZ?
The three-state output feature in the ISL59830IAZ allows each amplifier channel (ROUT, GOUT, BOUT) to be placed into high-impedance mode via the EN pin, isolating the output from downstream circuitry. With 25ns disable time and 200ns enable time, this supports glitch-free blanking during video source switching or power-down sequences in multi-channel systems. When disabled, output impedance exceeds 10MΩ, preventing loading of terminated video lines and eliminating crosstalk between active and inactive channels - a key advantage over open-collector or passive switch alternatives in analog video matrix applications.
Is the ISL59830IAZ still recommended for new designs?
No, the ISL59830IAZ is explicitly marked "NOT RECOMMENDED FOR NEW DESIGNS" in the official datasheet (FN7489 Rev.1.00), with Intersil recommending the pin-compatible ISL59833IAZ as an upgrade. The ISL59833IAZ improves upon ISL59830IAZ with tighter differential gain (0.05% vs. 0.07%), lower quiescent current (15mA vs. 120mA enabled), and enhanced thermal performance - while retaining identical pinout, package, and functional interface. For legacy repair or continuity builds, ISL59830IAZ remains available; however, new designs should specify ISL59833IAZ to ensure long-term supply and performance optimization.
